Hello everyone. I am the official radio guy for my unit where we use a technosonic 7000 to talk to multiple agencies and use the motorola astro25 cps to program upgrades. Unfortunately, we learn through trial and error instead of taking official lessons and learning from a pro. With that, all these terms such as carrier squealch, pl tones, and trunking are new terms for me. This website seems to be a good start but i couldnt find a forum that will guide me in figuring out the astro software. If im missing, can someone please link me to it. Thanks.
